    Hey mate late reply but just worked out you can use trimble grid factory to convert NTv2 files

    Well I know that but all other surveying and gis softwares support ntv2 so why Trimble doesn't? It is using all over the world.

    Hi Josh,

    Any suggestions on how this could be executed on the GDA94 to GDA2020 NTv2 GSB files? Especially "GDA94_GDA2020_conformal.gsb" https://github.com/icsm-au/transformation_grids 

     

    It'd be very handy to have this converted and it's inverse (GDA2020 to GDA94), for say using better heighting from AusGeoid2020, with GDA94 coodinates (via a VRS Now GDA2020 Stream), until all the States legislate to start using GDA2020, or the vast amount of users legacy data on GDA94...

     

    Cheers,

    Liam

    If you want import gsb to TBC it can be done. Also I think that transformation from GDA2020 to GDA94 can be implemented
